Development of Porous Rubber Pavement for the Canadian Climate
Porous Rubber Pavement (PRP) is a new type of permeable pavement in North America. It consists of stone aggregates, crumb rubber from recycled tires, and polyurethane as a binder. Due to a higher percentage of air voids (27% to 29%) and flexible nature, it offers extensive environmental and safety benefits, including improved stormwater management, reduced skid resistance, hydroplaning and greater potential for road traffic noise reduction. In the North American context, this material is currently used for low traffic roads and pedestrian walkways as a surface material. Because of the recent initiation, the performance, and the material properties of PRPs are not fully quantified yet. The main objective of this study is to explore the material properties and improve its performance in the Canadian climate as a pavement surface material for low trafficked areas. Working through this new type of porous paving provides substantial benefits for the partner, which will be realized through an extensive study within the project period. And that will be achieved through delivering a guideline helps the partners to optimize their raw materials and optimize their designs and selection.
